We all want the safest environment for our children, so why not add an air purifying plant to their room?
The Snake Plant is one of my favs, also referred to as "mother-in-laws tongue" is known to absorb nitrogen oxides and formaldehyde
I personally like its strong vertical structure and the varying degrees of green.
So...is there a spot in your house that needs a plant? I'd look into the other plant options that purify the air.
